wordpress修改固定链接后301重定向的方法

wordpress修改固定链接后301重定向的方法详细介绍

这篇文章主要介绍了wordpress修改固定链接后301重定向的方法,需要的朋友可以参考下

以前小站的固定链接好不人性化,结构是/%year%/%monthnum%/%postname%/,这样看起来又不直观又长的,今天做了一个301重定向,然后修改了新的固定链接,现在的固定链接格式是/%postname%.,这样看起来短了好多,也直观了好多,
不过小站已经被搜索引擎收录了好多,以前的地址都无法访问了,所以要做好301重定向,跳转到新的固定链接所生成的地址中去.要不然都是404就悲剧了.下面贴出解决办法

代码如下:

$rewrite_config = array();

$rewrite_config['highpriority'] = true ;

$rewrite_config['rewrite'] = array();

$rewrite_config['oldstructure'] = "/%year%/%monthnum%/%pos
mXlWNRDKtname%/";

function daxue_pm_the_posts($post) {

global $wp;

global $wp_rewrite;

global $rewrite_config;

$rewrite_config['rewrite'] = $wp_rewrite->generate_rewrite_rule($rewrite_config['oldstructure'], false, true, true, true);

if ($post != NULL &
amp;& is_single() && $rewrite_config['oldstructure'] != $wp_rewrite->permalink_structure) {

if (array_key_exists($wp->matched_rule, $rewrite_config['rewrite'])) {

// ok
, we need to generate a 301 Permanent redirect here.

header("HTTP/1.1 301 Moved Permanently", TRUE, 301);

header('Status: 301 Moved Permanently
');

$permalink = get_permalink($post[0]->ID);

if (is_feed()) {

$permalink = trailingslashit($permalink) . 'feed/';

}

header("Location: ".
$permalink);

exit();

}

}

return $post;

}

function wpdaxue_pm_post_rewrite_rules($rules) {

global $wp_rewrite;

global $rewrite_config;

$oldstruct = $rewrite_config['oldstructure'];

if ($oldstruct != NULL && $oldstruct != $wp_rewrite->permalink_structure) {

$rewrite_config['rewrite'] = $wp_rewrite->generate_rewrite_rule($oldstruct, false, true, true, true);

if ($rewrite_config ['highpriority'] == true) {

return array_merge($rewrite_config['rewrite'], $rules);

} else {

return array_merge($rules, $rewrite_config['rewrite']);

}

}

return $rules;

}

add_filter('the_posts', 'wpdaxue_pm_the_posts', 20);

add_filter('post_rewrite_rules', 'wpdaxue_pm_post_rewrite_rules');

将我的$rewrite_config['oldstructure'] = “/%year%/%monthnum%/%postname%/”后面的/%year%/%monthnum%/%postname%/修改成你自己的旧的固定链接格式,然后将这段代码加入到主题的function.中,然后设置成新的固定链接格式就搞定了.
